`font-lock-add-keywords' breaks existing keywords (or something like that)

[Oliver Scholz]

CVS from today: Starting from emacs -q --no-site-file eval the
following:

(progn
  (switch-to-buffer (generate-new-buffer "*tmp*"))
  (emacs-lisp-mode)
  (font-lock-mode 1)
  ;; This is the evildoer:
  (font-lock-add-keywords nil '(("lirum larum" . font-lock-warning-face)))
  ;; Examples:
  (insert ";; Strings and comments work o.k.:\n" "\"this is a string\"\n\n")
  (insert ";; The new keyword is highlighted correctly:\n" "lirum larum\n\n")
  (insert ";; But this is not hightlighted correctly:\n")
  (insert "(defun lirum-larum ()\n  (save-excursion\n    (message \"lirum 
larum\"))))"))
